Edit /etc/iscsi/initiatorname.iscsi: There may be some warnings in the file about editing the file, but don't worry. The key thing is the name you use must be unique to the iSCSI device you are connecting to. There should only be one line that is not commented out in the file. More than likely, it will look something like this:

InitiatorName=iqn.1994-05.com.redhat:28cdd2240a5

Change the part afer the ":" to be linux-"yourdnsname", where yourdnsname is the fully qualified DNS name of your machine. For example:

InitiatorName=iqn.1994-05.com.redhat:linux-case.doit.wisc.edu

Edit /etc/iscsi/iscsi.conf: Edit the following options or just add them to the end of the file if they are already commented out:
